Answer:

Initial value is \frac{1}{2}.

Step-by-step explanation:

Let us assume that the exponential function is f(x) = a(b)^{x} ...... (1)

Now, the point (0,\frac{1}{2}) will satisfy the above equation.

Now, this point on the graph of the exponential function will be sufficient to find the initial value of the function (1) i.e. a.

Now, putting the value x = 0 and y = \frac{1}{2} in the equation (1) we get, f(x) = a(b)^{x}

⇒ \frac{1}{2} = a(b)^{0} = a

⇒ a = \frac{1}{2} (Answer)

The radius of a wheel is 21m.how much distance will it covers when it rotates 5 times?​
mrs_skeptik [129]

Answer:

Distance = 660 meters

Step-by-step explanation:

Given the following data;

Radius, r = 21 m

Number of revolutions = 5 times

To find the distance covered;

The distance covered in one revolution is given by the circumference of a circle.

Mathematically, circumfeence of a circle is equal to;

C = 2πr

Substituting into the formula, we have;

C = 2 * 22/7 * 21

C = 44 * 3

C = 132 meters

Next, we find the distance covered;

Distance = Circumference * Number of revolutions

Distance = 132 * 5

Distance = 660 meters

A line passes through the point (-4,6) and has a slope of 5/4
kondaur [170]

Answer:

4y-5x-44=0

Step-by-step explanation:

It passes through one point with the formula being

y-y1=m(x-x1)

y-6=5/4(x-(-4))

y-6=5/4(x+4)

cross multiply

4(y-6)=5(x+4)

4y-24=5x+20

collect like terms

4y-5x=20+24

4y-5x=44

4y-5x-44=0

Taxi A charges $0.20 per mile and an initial fee of $4. Taxi B charges $0.40 per mile and an initial fee of $2. Write an inequal
Paraphin [41]
Well, for taxi A we have:

Cost of Taxi A = $ 0.20*X + $4
With "X" equal to "miles traveled".
For taxi B we have:
Cost of Taxi B = $ 0.40*X + $2
Then, when
Cost of Taxi B > Cost of Taxi A,

We Have:
$ 0.40*X + $2 > $ 0.20*X + $4

That is the inequality that you need!
Good luck!
